“…In fact, radiation‐induced luminescence phenomena related to the Cu + in Cu‐doped glasses have been widely investigated. However, many of these studies have focused on the thermoluminescence, optically stimulated luminescence, lyo—and mechano‐luminescence phenomena, or scintillation properties . Investigations of the RPL phenomena of Cu are very limited .…”

Radiophotoluminescence phenomena have been widely investigated on various types of materials for dosimetry applications. We report that an aluminoborosilicate glass containing 0.005 mol% copper exhibits intense photoluminescence in the visible region induced by X‐ray and γ‐ray irradiation. The luminescence is assigned to the 3d94s1 → 3d10 transition of Cu+. The proportionality of the intensity of the induced photoluminescence to the irradiation dose was confirmed up to 0.5 kGy using 60Co γ‐ray irradiation. Based on the spectroscopic results, a potential mechanism was proposed for the enhancement of the photoluminescence. The exposure to the ionizing radiation generates electron‐hole pairs in the glass, and the electrons are subsequently captured by the Cu2+ ions, which are converted to Cu+ and emit the luminescence. For the glass containing 0.01 mol% copper, the pronounced enhancement of the photoluminescence was not observed because the reverse reaction, ie, the capture of the holes by the Cu+ ions, becomes prominent. The photoluminescence induced by the irradiation was stably observed for the glasses kept at room temperature and even for the glasses heat‐treated at 150°C. However, the induced photoluminescence could be eliminated by the heat treatment at a temperature at 500°C, and the glass returned to the initial pre‐irradiation state. The Cu‐doped aluminoborosilicate glass is a potential candidate for use in dosimetry applications.

“…Cu incorporated in the core of germano-silicate optical fiber is known to exist as Cu 2+ and Cu + ions in the glass network during the high temperature fiber fabrication process [12,13]. And we have found that the Cu ions are involved in the formation of radiation-induced defect centers in the optical fiber that affect the magneto-optical properties.…”

We studied on the visible emission of Cu-ion-doped perovskite hafnate SrHfO 3 (SHO:Cu) with the photo-excitation energy dependence. The polycrystalline SHO:Cu samples were newly synthesized in the solid state reaction method. From the X-ray diffraction measurement it was found that the crystalline structure of SHO:Cu is nearly identical to that of undoped SrHfO 3 . Interestingly, the photoluminescence excitation (PLE) spectra change significantly with the emission energy, which is linked to the strong dependence of the visible emission on the photo-excitation energy. This unusual emission behavior is likely to be associated with the mixed valence states of the doped Cu ions, which were revealed by X-ray photoelectron spectroscopy. We compared our finding of tunable visible emission in the SHO:Cu compounds with the cases of similar materials, SrTiO 3 and SrZrO 3 with Cu-ion-doping.
